Ultradot began over 35 years ago with the creation of the UD25B, the first sight to use the red dot aiming system technology. The sight continues to be our workhorse with the only changes being upgrades to the electronics. Over the years we have expanded the line to offer our customers different features to improve their shooting experience, currently at eight models, soon to be nine. At Ultradot we strive to offer a dependable and affordable sight, something that you can count on.  (less)
